  6. Monitor Seeds Daily: Check moisture level of paper towels and add water as needed to keep them consistently moist.

Seedling Stage

Seedling Stage

The seedling stage is a critical period in the grow of cannabis plant, as it sets foundation for healthy and vibrant grow.

During this stage young plants are establishing their root systems and beginning to produce their first sets of leaves.

The tiny sprouts emerge from their germination medium, revealing their cotyledon leaves – essential for absorbing light and providing seedlings with energy to continue growing.

It’s crucial to ensure that the seedlings receive adequate light and humidity, while being careful not to overwater them.

Maintaining consistent environment with a temperature of around 70-75°F (21-24°C) is vital for optimal grow.

In the second weeks, seedlings start developing their first true sets of leaves, which have iconic serrated edges and cannabis leaf shape.

It’s important to monitor grow and overall health during this period, as any issues that arise can significantly impact its future development.

Make sure to provide the seedlings with sufficient light, water, and air circulation while avoiding any sudden changes in their environment.

By the third weeks, seedlings have multiple sets of true leaves and robust root systems.

This is a great time to consider transplanting the young plants into larger containers to provide them with more room to grow and develop.

The seedling stage is a crucial part of grow and development of cannabis plant, setting foundation for healthy and thriving future.

Vegetative Stage

Vegetative Stage

The vegetative grow stage is an essential milestone in the grow cycle of marijuana as it is a time when plants focus on building up their structure, strength, and leaf.

During this phase, it’s crucial to provide your plants with ample amounts of light.

Indoor growers should aim for at least 18 hours of light per day, with some experts suggesting up to 24 hours for optimal grow.

Outdoors, natural sunlight will benefit your marijuana and they should be positioned in spot that receives maximum daylight exposure.

Nutrition is another critical factor during the vegetative phase. Your plants will need balanced diet of nutrients, with a particular focus on nitrogen, phosphorus, and potassium.

Nitrogen is especially important at this stage, as it plays a crucial role in development of chlorophyll and amino acids that are vital for healthy plant grow.
